Is the DbContext class defined and used differently in the version of C# for Visual Studio 2012 than in Visual Studio 2010?
I am using code written under Visual Studio 2010 as an example for a project I am writing for with Visual Studio 2012. I am having some difficulty using the DBContext class to instantiate a class. The code seems to required using the namespace System.Data.Entity.Infrastructure; and that does not seem to be defined in the newer System.Data.Entity reference.
To show you what I mean in coding terms, this is the line of code that does not compile:
This is the code snap shot in the Visual Studio 2012 that does not compile:
It seems that "Infrastructure" is a component of "systems.data.entry.dll" that I have set as a reference:
But wait, there is more. The code, as it exists in the visual studio 2012, is copied from code from a project that does, in fact, compile in visual studio 2010.
Notice, that there is no little red curly line under Infrastructure when I declare that I am using the namespace System.Data.Entity.Infrastructure in Visual Studio 2010:
The research I have done on this issue has lead to a dead-end. This seems to be some sort of required add-in according to this web page::
You see, the problem seems to be centered around declaring and using the DbContext class. But when I tried running this program from Microsoft after I downloaded it, it showed me that it was not for Visual Studio 2012.
